The lack of fairness comes from the way the ecosystem is setup, you have
the reference compiler released, then everybody needs to catch up with
it. Why not have others be part of the official release? This will
undoubtedly increase the quality of the frontend and the glue layer, and
probably the runtime, just because they will be tested on more
architectures each release.
No matter how you put it, both LDC and GDC are limited in manpower, and
also caught in the merge game with mainline. This is a bottle neck if
they need to attract more talent. Right of the bat you need to do a lot
of grunt work handling different repos, each at their own revision, plus
all the knowledge about build env and testing env.
The issue here is the front-end not the back end. Daniel has already
stated this was a goal (to make the front end shared code). So it will
happen (I think Daniel has a pretty good record of following through,
we do have a D-based front end now after all).
Any effort to make both LDC and GDC part of the "official" release
would be artificial -- instead of LDC and GDC getting released
"faster", they would simply hold up dmd's release until they caught
up. And this is probably more pressure than their developers need.
When the front end is shared, then the releases will be quicker, and
you can be happier with it.
OK, a shared front end will be great!
My main concern is that if they are not integrated withing the daily
pull-merge-auto-test loop they will always tend to drift and get out of
sync while trying to fix stuff that breaks.
I think the intention is to make all of the compilers supported with
some reasonable form of CI (not sure if all PRs would be tested this
way, because that may be too much of a burden on the test servers).
The idea is that ldc and gdc will get plenty of warning if something breaks.
